I know 'Coinbase listing' has been beaten to a pulp, but recently saw this. Not sure if this is a viable route to a Coinbase listing for ICX, but should be explored nonetheless.
The power of Coinbase is undeniable; institutional investors are flocking to Coinbase for Crypto. Large bitcoin outflows to private wallets (+$10mm) are predominately driven by institutions and Coinbase is 80% of that volume - see key takeaway below:
"Surprisingly, **supply on exchanges declined from 2.418m to 2.344m,** with Coinbase accounting for 80% of those outflows."
With institutions moving into altcoins next, I hope ICX will have a presence on Coinbase.
